Alpha radiation detector SIID

particleion

Application Silicon Ion Implanted Alpha Detectors are designed to enable precise alpha spectroscopy. The thin entrance window of the detectors provides good energy resolution even in close proximity alpha radioactive source providing high efficiency registration of alpha particles. Features The detectors can operate without hermetization due to location of P-N junction inside of the detector crystal Contacts are formed using ion-implantation method and provide thin, well-formed junctions Relatively thin dead layer (less than 500 Å) High solidity entrance window Can work in vacuum Possibility of annealing the detectors up to 100 °C The detectors may be packed in different kinds of packages with BNC or MICRODOT connectors or wire leads adapted for different customer’s needs The detectors are produced with open window or with metalized window A special version of the Ion Implanted Silicon Alpha Particle Detectors with metalized coating of entrance window allows the detector to monitor radioactive aerosols. This is special version of the detectors with characteristic features: Allows the detector operation in ambient light The metal coating provides mechanical and chemical protection. The thickness of entrance window is less than 2 μm Can be operated at bias voltage - from +15 to +24 V DESCRIPTION Silicon Ion Implanted Alpha Detectors enable precise alpha particle spectroscopy. The thin entrance window of the detectors provides good energy resolution even in close proximity of the alpha radioactive source and also provides high efficiency registration of alpha particles.
